Lumbar CamelBak

Verified Buyer Reviewed by Selah Walker from Washington on Monday, May 9, 2016
Second one I've own. CamelBak changed designed, this one doesn't slip as much as the older version, because they changed the belt and the bag holder inside the belt. It didn't slip on the marathon I just finished. And yes, it will bounce if your "fast" but if you walk or jog slow it doesn't bounce around. They changed the pockets, so the pockets are more upright and not slanted so if you open while "running" or walking stuff won't fall out if not secured in the webbed pockets. Not as much reflective piping on the back as previous model. I only adjusted my belt once during the marathon (this is typical because of weight loss during the race even with fluid consumption). I do not clip the tubing to my clothes, I tuck it in the belt so I can just pull it up, this works for me so I don't hit it or get tangled up in it.
I like this CamelBak because it leaves my arms/hands free for arm swing, I'm a race walker. I do not have any type of back discomfort from this CamelBak and I can carry my gels/cellphone/keys.
